As with the rest of this website, I am adding new things every day. This is all there is at the moment.
This original photo has too much red tone, the cat has a mole on his chin and his eyes are actually green.
The image is crooked and again, there is too much red in the overall tone of the image. In addition, the statue is fuzzy and lacks contrast.
There is graffiti in the lower left area of the image and you can see bolt holes from earlier climbers on either side of the image.
In the retouched photo, the color is corrected as is the cat's chin, his tongue and nose are "pinked", the background has been removed and colored outlines added. It was a short step from here to the GIF logo.
Now, the color has been corrected, the statue pops-out more and the overall look is much brighter. Notice too that the yellow tulip in the lower-left foreground is now red, so that a nice diagonal line is created to draw your eye over the picture.
Here, you see the graffiti has been removed and the bolt holes are gone.
